Groundwater Clean-Up Aided by Silver Chloride

摘要

A contractor at the U.S. Department of Energy's Savannah River Site (SRS) is cutting groundwater clean-up costs by almost US$11 million annually by injecting silver chloride into the aquifer.The silver chloride mixes with iodine-129 - a by-product of nuclear reactions - forming harmless silver iodide. Previously, contractor Savannah River Nuclear Solutions (SNRS) used more expensive mitigation techniques involving highly-mechanized pumps and treatment facilities.
